Remote | Full-time

Compensation: $170K - $220K

We are hiring on behalf of our client in the decentralized finance (DeFi) sector who is seeking a visionary Chief Marketing Officer (CMO) to define and lead the narrative for a groundbreaking market structure. The client is pioneering the first-ever Proprietary Automated Market Maker (Prop AMM) DEX on the Ethereum and EVM L2 ecosystems.

By leveraging advanced modular infrastructure, this platform addresses traditional limitations regarding high storage costs and non-deterministic transaction ordering. The result is a system that protects liquidity providers from toxic order flow while providing end-users with the most competitive prices and tightest spreads on-chain.

The CMO will be responsible for categorizing "Prop AMM on EVM" as a new industry standard and positioning the client’s platform as the dominant leader in this space. Working directly with the CEO, CTO, and CPO, the successful candidate will own the brand, growth loops, and go-to-market strategy for a product designed to outcompete both centralized and decentralized exchanges.
